Introduction

The introduction of gas control barriers in cavities dictates one installs means by which all arrested gas and water can be routed out of the structure. Additionally, where services penetrate any membrane or barrier the entry point must be suitably sealed. A range of accessories are available for this purpose:

Cavibricks may be installed in the external skin under barriers to discharge gas in the cavity trapped below barrier level.

Caviweeps may be installed within perp joints to discharge penetrating water arrested on the upper surface of the barrier. (drawing)

Service Pipe Entry Points are preformed sleeves via which service pipes may enter the structure. These are bonded to the protective membrane.

Use

Discharge routes for arrested methane and radon gas. Discharge routes for water arrested by barriers. Sleeves for service entry points.
